One of my favorite sayings is “Nothing fancy, just results”. That is how we train at the Cave and we do get ongoing, measurable results. All of our athletes are tested every 3 months to make they are progressing.
Without a solid foundation of basics you have nothing to build on. That is true of any and all types of physical training.
I taught and practiced  martial arts for many years, the basics were drilled into us, over and over again. The basics have  never let us down.
More intricate and complex movements would be learned only after a person had quite a bot of experience.
The same goes for Mace Fit, a solid foundation of basics must be built first!
